How to kill a swamp (red) maple
I am planting a Atlantic White cedar swamp along my stream but there is a big nasty red maple crowding out everything. It roots are like iron and it shaded the whole wet area.
The problem is that my wife is neurotic about not cutting down trees. We have 4 acres and 500 acres behind us full of trees so you would think that cutting one would not be a big deal but it is.
How can I discreetly kill that rotten tree? It would be very hard to girdle underground. I have lopped off branches and sprayed the wound with roundout to no effect. help.
